Imbibition is involved in

Options

A. Supply of `CO_(2)` during photosynthesis
B. Opening and closing movement of stomata
C. For the germination of seeds
D. Movement of water from one cell to other cell

Answer

**Step-by-Step Solution:**

1. **Understanding Imbibition**: Imbibition is defined as the process of adsorption of water by solid particles of a substance without forming a solution. This means that water is absorbed by the solid material, causing it to swell.

**Hint**: Remember that imbibition involves solid materials absorbing water, not dissolving it.

2. **Mechanism of Imbibition**: Imbibition occurs due to the kinetic energy of water molecules. Water moves from areas of higher concentration (more water) to areas of lower concentration (less water). This movement can be influenced by diffusion or capillary action.

**Hint**: Focus on how water moves from high to low concentration, which is a key concept in understanding imbibition.

3. **Identifying the Role of Imbibition**: Imbibition is crucial in various biological processes. One significant role is in the germination of seeds, where seeds absorb water to swell and activate metabolic processes necessary for growth.

**Hint**: Think about processes in plants that require water absorption, especially during the early stages of growth.

4. **Analyzing the Options**:
- **Option A**: Supply of CO2 during photosynthesis - This is not related to imbibition.
- **Option B**: Opening and closing movement of stomata - This involves turgor pressure but is not directly related to imbibition.
- **Option C**: Germination of seeds - This is related to imbibition as seeds absorb water to germinate.
- **Option D**: Movement of water from one cell to another cell - This is also a function of imbibition.

5. **Conclusion**: While both options C and D are related to imbibition, the most direct answer to the question "Imbibition is involved in" is option D, which specifically refers to the movement of water from one cell to another cell.

**Final Answer**: Option D - movement of water from one cell to another cell.
